react-relay VS react-query

Suppose we have this JavaScript file from Relay, a GraphQL client framework.

Relay is a JavaScript framework for building data-driven React applications.

Relay 17 Improved correctness checking and validation; Additional editor features; Experimental features exploring error handling and nullability

GraphQL Relay is one of the most powerful GraphQL clients that you can found on the web environment. It provides to you a lot of features that lets your development flow in a scalable way.

GQty (https://gqty.dev/) and Relay (https://relay.dev/) will combine fragments or queries you request in your React components and will handle combining these / getting the data each component needs with as few queries as is possible. Are there any other clients I’ve missed? It’s not immediately clear to me whether this is possible with Urql via Exchanges (https://formidable.com/open-source/urql/docs/advanced/authoring-exchanges/).

Inside Woovi, our entire codebase is managed by GraphQL using the Relay client framework. To ensure the best UX possible for our final user, we give some useful features in our payment link, like the real-time update after paying a charge. It's all handled by our GraphQL, which won't be solvable by templates in our use case.

Since you mentioned Node CRUD APIs, I'd probably suggest looking at Relay/GraphQL. Would give you exposure to some interesting and employable skills that wouldn't require you learning an entirely new domain on top of it. They are rewriting the current compiler in Rust, which since you mentioned Rust might be interesting to follow. Uneducated takes, but GraphQL is a schema IDL, so would probably be a good place to start to minimize lexical complexity while still having some cool abstract concepts to learn (interfaces, unions, etc).

You may be familiar with Global Object Identification(GOI), especially if you've used Relay.

react-query

React Query: This library makes it easy to manage data in your React applications, from fetching to caching and updating data. It offers a simple, powerful, and flexible API for handling data and keeping your UI in sync with your data. https://github.com/tannerlinsley/react-query

useQuery (react-query) (+) all from above (+) even more features (-) more complex, even the examples are complex, has more aggressive defaults (re-fetching every 2s)

see here Overview

Rapini is a new tool that can generate custom React Query hooks using OpenAPI (Swagger) files.

React Query is the gold standard for using async data declaratively with hooks. I ended up needing to modify even my simple useTimer hook to work more like useQuery to take multiple keys in order to work as an inner observable for other operators.

For most situations, I would recommend using a library like React Query. It handles a lot of common data-fetching boiler plate and already accounts for this useEffect() issue. Also, it supports Suspense if you want to use that.

At this point, I want to move on to the react-query cache management library. Give a brief overview and see how you can improve your developer experience with cache using this library.

There isn't the "service" concept in React. If you need to send off data you can just do so with fetch. If you need to load data and cache it so it can be used across components and unmounts, then something like react-query is what I'd recommend. But it's basically a combination of React Context, useEffect, and useState to manage the cache and lifecycle of a request.

react-query is pretty neat too. I default to that for most projects unless it's something unusual
